Introduce the add_service() macro which wraps up add/find
permissions for the source domain with a neverallow preventing
others from adding it. Only a particular domain should
add a particular service.
Use the add_service() macro to automatically add a neverallow
that prevents other domains from adding the service.
mediadrmserver was adding services labeled mediaserver_service.
Drop the add permission as it should just need the find
permission.
Additionally, the macro adds the { add find } permission which
causes some existing neverallow's to assert. Adjust those
neverallow's so "self" can always find.
Test: compile and run on hikey and emulator. No new denials were
found, and all services, where applicable, seem to be running OK.
